Looking at Geo Ottawa, they do seem to be on City property. Given that the plans call for (at least some) trees along Lees, this is really stupid and frustrating.
And the tree butchering continues. The poor folks in the townhomes off Chapel are getting more direct sunlight in their homes than they've had in decades. It looks like they only stopped where they did because one of the trees is leaning heavily toward the building and they wouldn't have been able to take it down (with the excavator no less) without it falling on the houses. I'm guessing they'll bring in an arborist to deal with that and then continue removing the large cluster of trees in the northern corner of the property.
